MULTIPLE-SHARE PLOW.

Specification of Letters Patent.

Patented Mar. 28, 1922.

Application filed August 11, 19 19. SerialNo. 316,859.

To all whom it may concern:

Be it known that I, EDMOND Him, a citizen of the French Republic, residing at No. 57 Rue Josephine, Evreux, Eure, France, have invented certain new and useful Improvements in Multiple-Share Plows, of c which the following is a specification;

The present invention relates to improvements in multiple share plows and has for its object to provide a plow which is capable on its arrival at the end of the field after plowing a furrow to resume the plowingof the next furrow at that end and thus avoid missing a furrow. At the same time doing away with an idle travel over thefield and buildings to a minimum.

In the accompanying drawings which illustrate by way f example a constructional form of this invention,

Fig. 1 is a side view of the. improved plow,

Fig. 2 is a plan thereof,.

Fig. Sis a rear end view of the improved plow in operation, s Fig. 4 is afrontend view of the plow in condition for transport,

Fig. 5 is anelevation of a detail of which Fig. 6 is afront view,

a Fig. 7 is an elevation of another detail illustrating the-rear adjustment device for the depth of working,

Fig. 8 is an elevation of another detail illustrating the front adjustment devicefor the depth'of working,

Fig. 9 is a back view of a detail illustrating an arrangement for rocking of'the body of the plow.

V The improved-plow consists essentially .of

I [this shaft 9 rests in abracket 11 carried by the underecarriage. The bearing 12 and the two parts, namely,

Anunder-carriage, and

p1owshares. 1 1

The under-carriage consists of a longitudim1 frame 1 supported by. two front wheels; I

fcomprisesa rear bearing l iand a front bear- 2 Q y and two hind wheels 3, 3?.

The hind wheels are mounted ona transverselyrotatable axles capable of pivoting ried by the plates 8.

A- longitudinal frame for carrying the forcearefixed to the under-carriage 1, Figs.

.5and. 6.

around a horizontal pivot 5 fixed to an adj usting screw 5 sliding in. amember 1 fixed behind the frame 1 and atthe end of a shaft 9, the said adjusting screw 5" being actuated by means of a hand wheel 6."

In order to adjust the height of the wheels and therefore the depth of working, the

hand-wheel 6 is acted upon, which hand- .'Wl166l bears on a cross member (S and is screwed on the screw 5 raising or, lowering the undercarriage and the shaft 9 on the wheels 3 and 3.

Owing to this pivotal arrangement,one of thehind wheels is able to run in the furrow,

whilst the other wheel can run on the land,

that is to say, the ground which hasnotyet been plowed (Fig.

On the other hand, one of the front wheels 2, 2 isalso capable of running alternately in the furrow onfthe outward journey and on the unplowed groundon the return journey, without however, affecting the height relatively to the ground level of the hereinafter described frame that carries theplowshares, a

The regulation as to height which deter mines the depth of the plowing is effected,

once foriall at the beginning of the work in f the case of both front and hind wheels.

In the case of each of the frontwheels 2,2? this adjustment is effected by means of oted at 1 to vertical side platesS carried by the underframe- 1 By angularly adjustingthelevers 7 the height of the wheels 2, 2

with respect to the carriage 1 can be varied.

Eachlever 7 can be secured in adjusted position by means of pins or the like fitting in perforations in sectors 8 formed on orv car- The rear axle dis connected to the front part of theunder-carriage by. a longitudinal shaft 9 which serves as an axis for the rotation andas a support for'thefrarne 10 that carries the plow-shares. The front end of arc-shaped member 13 receiving thetractive Theframe 10, that carries plowshares ing15, by means of. which the frame 10 is frame consists of a double right-angled frame, see particularly Fig. 3, carry ng along each side the plowshares and colters, the plowshares on one side of the .t'rame being arranged to turn the soil to the r1ght,'wh1le the shares on the otherside are arranged to turn the soil to theleft- Thus, on both the outward and return journey the soil will be turned over to the same side. This result is produced by the transverse rocking movement of the two series of plowshares which act upon the ground alternately in the outward and return journeys over the field.

The rocking 0f the plowshares carrying frame 10 isefi'ected by meansfof a charm 16 "attached at each of the ends to thesides of the frame 10. This chain passes over and is driven by a pinion 17 inounted'ona member 17 secured to the arc-shaped member 13, and is actuated by the driverfrom his seat. The chain 1 6 is connected at 10? and 10 to perpendicular parts of the frame 10, a spring '18 being interposed between the. plowsharecarrying frame 10 and thechain 16 t'orthe purpose of softeningthe' shock of the motion and for causing the plowshares to penetrate gradually into the ground. r fBy this arrangement the frame 10 will always be perfectly parallel to the ground level,whatever may be the inclinationof the I3? in the member-13 supporting wheels. 7 e

The tractive'force is transmitted to the plow by the hearing. 15 having the {form ofa circular sleeve withi a collar, made in one piece with the plow frame 10. This'bearing 15 which is carried by the shaft adapted in its turn to revolve uporr the bearin'g 12 which is fixed to the i1nder-carriage 1, Figs. 5W n i s r 'dthe e h e a p 12 of the bearing 12'and by two hooks 19 fixedto the frame '10 andadapted tobear and slide o'n an arcshaped member l 3 to the under-carriage. I

By this arrangement theitraction is always assured irrespectively of the position of the plowshar'e frame.
